Experimental investigation of optimal operation time for a double effect adsorption refrigeration cycle

The objective of this study is to find the optimum operating time for a double effect adsorption refrigeration cycle with adsorption heat recovery. Adsorption refrigerators are used to utilize low-temperature heat to produce cooling. In this study, an experimental equipment was made to examine the performance of the double effect scheme with adsorption heat recovery. Heat from the adsorbent FAM-Z02 is transferred to silica gel bed for the desorption process. The behavior of the cycle was observed experimentally which indicates the regeneration of the adsorbent worked successfully with the adsorption heat at the heat source temperature of 85℃. Furthermore, the effect of adsorption / desorption time on the cooling performance was investigated, which reveals there is an optimal time to maximize COP.
